Methane is emitted in horizontal subsurface flow constructed wetlands (HSSF CWs) during wastewater treatment. The objective of this work was to determine the influence of primary treatment and organic loading rate on methane ...
Life cycle assessment of constructed wetland systems for wastewater treatment coupled with microbial fuel cells
(2017-04)
Article.
Accés obert
Article.
Accés obert
The aim of this study was to assess the environmental impact of microbial fuel cells (MFCs) implemented in constructed wetlands (CWs). To this aim a life cycle assessment (LCA) was carried out comparing three scenarios: ...
Microbial activity enhancement in constructed wetlands operated as bioelectrochemical systems
(2022-01)
Article.
Accés obert
Article.
Accés obert
Treatment wetlands (TW) operated as bioelectrochemical systems (BES-TW) provide a higher degree of treatment than conventional TW. Yet, the fundamental processes or mechanisms for the envisaged better performance of BES-TW ...
MFC-based biosensor for domestic wastewater COD assessment in constructed wetlands
(Elsevier, 2019-04)
Article.
Accés obert
Article.
Accés obert
In the context of natural-based wastewater treatment technologies (such as constructed wetlands - CW) the use of a low-cost, continuous-like biosensor tool for the assessment of operational conditions is of key importance ...
Long-term assessment of best cathode position to maximise microbial fuel cell performance in horizontal subsurface flow constructed wetlands
(Elsevier, 2016-09)
Article.
Accés obert
Article.
Accés obert
The cathode of microbial fuel cells (MFCs) implemented in constructed wetlands (CWs) is generally set in close contact with water surface to provide a rich oxygen environment. However, water level variations caused by ...
Electrochemical characterization of Geobacter lovleyi identifies limitations of microbial fuel cell performance in constructed wetlands
(2017-04)
Article.
Accés obert
Article.
Accés obert
Microbial Fuel Cells implemented in Constructed Wetlands (CW-MFCs) show limited performance. Geobacter Lovleyi has been demonstrated to be one of the predominant bacterial species in active CW-MFCs. The aim of this study ...
Microbial fuel cells for clogging assessment in constructed wetlands
(2016-11)
Article.
Accés obert
Article.
Accés obert
Clogging in HSSF CW may result in a reduction of system's life-span or treatment efficiency. Current available techniques to assess the degree of clogging in HSSF CW are time consuming and cannot be applied on a continuous ...
Improving domestic wastewater treatment efficiency with constructed wetland microbial fuel cells: influence of anode material and external resistance
(Elsevier, 2018-08)
Article.
Accés obert
Article.
Accés obert
For the past few years, there has been an increasing interest in the operation of constructed wetlands as microbial fuel cells (CW-MFCs) for both the improvement of wastewater treatment efficiency and the production of ...
